Problem: In public-transit-friendly Germany, seniors affected with Alzheimer's can end up half way across the country before anyone knows they're gone.
This probably wouldn't work well in the US, because our public transit systems aren't as strong or extensive. But it is a thought.
Is it wrong that my first thought was putting a hunting blind near them and solving a few problems at once?
SHAME on you, Ron. I am so sorry that I won't be around for you to hit this age and perhaps have these problems.
